Quaas et al. 2015

During Phase 1 (2007-2012), the joint GEWEX/Integrated Land Ecosystem Atmosphere Processes Study (iLEAPS) Aerosols-Clouds-Precipitation and Climate (ACPC) initiative demonstrated the diverse effects that aerosols exert on precipitation. Stevens and Feingold (2009) argued that in many cases cloud-precipitation systems tend to buffer or dampen the amplitude of the aerosol effects. ACPC then reviewed global observations related to aerosol-cloud-precipitation-climate interactions and how a field campaign could be designed to go beyond the existing data sets in fully characterizing the energy and water budgets for varying aerosol conditions.

The ACPC initiative started its second phase in late 2013. The first workshop in this phase was held on 8-10 April 2015 at the NASA Goddard Institute for Space Studies (GISS) in New York to discuss such a possible future field campaign design and potential roadmaps towards it. The focus was on the possibilities of exploiting high-resolution modeling with detailed microphysics to assess observational requirements and opportunities for such experiments.
